Where is that "Quote" locate ?

The tittle is kinda misleading, no i'm not talking about where is the Quote button ? 

I'm talking about when and where is that quote locate in the chat.

When someone quote other in a conversation and i just pass by. And i want to know what are they talking about, or just simply want join in a random conversation. It's kinda hard to just scroll up in a huge open chat just to know the content, about 100+ people, or in some case, that quote is from a long time ago. I know i can use search, and try to sort out others similar text. But extra feature to just click into that quote and it leads me to the original chat, would be really nice.
